从post方法获取数据后如何重定向

我有一个post method to servlet,因此servlet在将请求转发到另一个页面后返回一个网页
getServletContext().getRequestDispatcher("/AnotherServlet").forward(request, response);
所以我无法直接重定向window.location ="/Anotherservlet"我尝试了很多解决方案:通过链接传递参数并且它正在工作但我会更好一个我试过var w = window.open(); w.document.write(data);它是工作,但页面的网址仍然是我的主页,页面仍然加载甚至页面从服务器下载(所有功能与ready语句不工作)所以当我点击按钮与href =“#”它重定向到主页因为正如我在我的网址前说的那样= / not = / anotherervlet
我不喜欢得到方法或者为我寻找其他解决方案的cookie感谢您的帮助
这是我的servlet:

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {


    String name= request.getParameter("name");
    String pass=request.getParameter("pass");

     if (name.equals("a")&&pass.equals("0cc175b9c0f1b6a831c399e269772661"))
    {
    getServletContext().getRequestDispatcher("/BookListServlet").forward(request, response);
    }
    else 
    {
     response.setContentType("text/plain");
        PrintWriter out = response.getWriter();
        out.print("error");
        out.flush();
        out.close();
    }

}

这是我的BookListServlet:

 protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

    books= new bookiml().get_books();   
    String name= request.getParameter("name");
    String ipAddress = request.getRemoteAddr();

request.setAttribute("books", books);
request.setAttribute("userip", ipAddress);
request.setAttribute("user", name);
request.setAttribute("title", "Book listing");

getServletContext().getRequestDispatcher("/META-INF/pages/book-list.jsp").forward(request, response);
}

/**
 * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
 */
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    // TODO Auto-generated method stub
    doGet(request, response);
}

我在检查登录验证后不想从servlet获取页面,但是没有在链接中传递参数,如下所示:`

$.ajax({
                    url: 'identification',
                    type: 'POST',
                    data:{pass:$hash,name:$name},
                    timeout: 1000,
                    success: function(data){
                     var target = document.getElementById('spinner');
                                    spinner = new Spinner(opts).spin(target);
                                    $('#spinner').fadeIn();

                                    if (data=='error')
                                    {
                                    $("#messages").html(" Check your username and password.");
                                    $('#name').css('border-color','#B94A48');
                                    $('#pass').css('border-color','#B94A48');
                                    $('#spinner').fadeOut();
                                    }

                                    else 

                                        {
                                        $("#messages").html("");


            $('#spinner').fadeOut();
                                    window.location ="/BookListServlet?name="+$name;
                                    }


                }
            });`

据我了解,您只想使用servlet重定向?

response.setStatus(response.SC_MOVED_TEMPORARILY);
response.setHeader("Location", "http://splinky.com/");

您可以将url放在ajax响应中,以便在成功的情况下进行重写:

示例js响应:

{ status: 'ok', redirect: '/example' }

在客户端使用js重定向。

客户端代码:

$("form.ajaxForm").submit( function(e) {
        var form = $(this);
        form.ajaxSubmit({
            dataType: 'json',
            success: function(data) {
                if( data.redirect != "" ) {
                    window.location = data.redirect;
                }
            }
        });

        return false;
    });

你必须使用jQuery表单插件才能工作。请参阅:http://jquery.malsup.com/form/#getting-started
